OBJECTIVE: Retinopathy of prematurity (ROP) is an eye disease with the potential to cause blindness, primarily affecting premature infants with low birth weight. This study analyzed the etiology, primary location, and research advances in ROP.

MATERIALS AND METHODS: We used bibliometric techniques and searched the Web of Science Core Collection for “retinopathy of prematurity.” We found 4,018 original articles and reviews with 69,819 references. We analyzed the data using HistCite (12.03.17), VOSviewer (1.6.16), CiteSpace (6.1. R5), and the Bibliometrix Package (4.1.0).

RESULTS: The amount of literature in this area has increased between 2001-2021. An analysis of references and journal co-citations highlights this field’s most influential articles and related topics. Hellström, from the University of Gothenburg (Sweden), is the most prolific researcher; Harvard University is the most prolific research institution, and the USA is the most productive country. “Threshold ROP” and “cryotherapy” are the keywords with the highest burst strength. The future research hotspots are artificial intelligence, zone II, ROP development, ranibizumab, and type 1 retinopathy.

CONCLUSIONS: This article offers a comprehensive review of the present status of ROP research, along with insights into emerging concepts and potential international collaborations in this field.
